SD Card
A micro SD card is required to use custom configurations, to play WAV files, and to store vocalizer settings — such as vocalizations saved to memory — between sessions. Without an SD card, this information will be lost every time the Teensy is powered off.
An SD card rated V30 or faster is required for playing WAV files.
The card must be formatted as FAT16 or FAT32. Windows 11 no longer natively supports FAT formatting for cards larger than 32 GB, so you will need a 3rd party tool such as MiniTool Partition Wizard.
The SD card must be inserted into the reader on the Teensy itself as shown below— NOT the reader on the Audio Adapter.
